"It's plausible that the goodness and badness of everything ultimately cashes out in terms of the quality of people's experience. On this view, there are many worthy values: family, education, freedom, bravery, and all the rest of the values listed on the chalkboard. But, says utilitarianism, these things are valuable because, and only because, of their effects on our experience. Subtract from these things their positive effects on experience and their value is lost. In short, if it doesn't affect someone's experience, then it doesn't really matter."
